Frequently Asked Questions
We’ve been using Bio Shield for a few years with great results controlling the lichen build up on our roof tiles. It’s a great product. It’s good to know there’s companies out there that actually deliver on their promises.
Just wanted to say how thorougly impressed I am with Bio-Shield. All the claims you make on your website are true. The product works great. The Jet-Stream is a real time saver.
Don't normally write this sort of stuff, but was compelled by the quality of product and service
It's not often that a product lives up to the manufacturers advertising. All I can say is that i had my doubts after applying 2 other types of lichen removal products to my lichen covered colourbond roof which had limited affects. I applied bioshield as per instructions and nothing happened for a few weeks but now after several months my roof is completely free from lichen .
Great product used it successfully for years and only once when I had a minor concern the company sorted the problem out immediately . Would highly recommend, I also find Bio Shield much better value for money than other overpriced moss / lichen cleaning products constantly advertising themselves with saturation marketing.
Absolutely love this product. I have used it to restore family headstones that haven't been touched for nigh on 80 years. Highly recommended from me. Will be using as part of the New Zealand Remembrance Army restoration work too.
This is the second time i have used this product from this company. the service is unbelievable-paid one day and delivered the next day. confirmation of received order and then delivery advice with courier tracing details. their product is significantly cheaper than the major competition and works equally as well or perhaps even better in my experience.
